HAL114
Unipolar Hall Switch IC
in CMOS technology
Introduction
The HAL114 is a Hall switch produced in CMOS technol-
ogy. The sensor includes a temperature-compensated
Hall plate, a Schmitt trigger, and an open-drain output
transistor (see Fig. 2).
The HAL114 has a unipolar behavior: The output turns
low with a magnetic south pole on the branded side of
the package (see figures 3 and 4). The output turns high
if the magnetic field is removed. The output signal re-
mains high if the magnetic north pole approaches the
branded side of the package.
The sensor is designed for industrial and automotive ap-
plications and operates with supply voltages from 4.5 V
to 24 V in the ambient temperature range from â40°C up
to 150 °C.
The HAL114 is available in a SMD-package (SOT-89A)
and in a leaded version (TO-92UA).
Features:
â operates from 4.5 V to 24 V supply voltage
â overvoltage protection
â reverse-voltage protection at VDD-pin
â short-circuit protected open-drain output by thermal
shutdown
â operates with magnetic fields from DC to 20 kHz
â stable magnetic switching points over a wide supply
voltage range
â the decrease of magnetic flux density caused by rising
temperature in the sensor system is compensated by
a built-in negative temperature coefficient of the mag-
netic switching points
â ideal sensor for contactless switches and speed mea-
surement in hostile automotive and industrial environ-
ments
Specifications
â switching type: unipolar
â output turns low with magnetic south pole on branded
side of package
â output turns high if magnetic field is removed
